This knife gate valve can be specified with selectable pressure and sealing options. The actual pressure rating must match the ordered size and construction, and the selected seal must match the medium and operating conditions. Options are not a statement that every combination is available at every size.
Product Overview
The gate moves across the flow passage for the intended isolation duty. For a wear-related application, the medium, solids and operating pattern should be reviewed with the proposed gate and sealing arrangement. The page does not establish a universal wear life, unrestricted pressure choice or a single rating for the complete size range.
Selection and Ordering Notes
- State the required nominal size, design pressure, temperature and shutoff conditions.
- Request confirmation of the rating for that particular size and body construction.
- Choose the required sealing option from the quotation and confirm its compatibility with the process.
- Provide solids information, connection details, drive requirements and the installation and maintenance arrangement.

Frequently Asked Questions
Can I choose the pressure rating for this knife gate valve?
Pressure options can be requested, but the rating must be approved for the actual size and construction. Send the duty requirements rather than assuming every pressure option is available across the whole range.
Can I choose a different sealing material?
Yes, sealing options can be selected. Describe the fluid, solids, temperature and operating pattern and request confirmation of the proposed seal for the quoted assembly.
Does wear-resistant mean the gate and seals will have a guaranteed service life?
No numerical life or universal wear-resistance guarantee is established by the name. Supply the abrasive-service conditions and request the applicable material, maintenance and acceptance information.
